INLETeCONTROL VALVE FOR FLUSH-TANKS.

Specification of Letters Patent.

Patented Feb. 8,V 1921.

vApplication ledl'anuary 7, 1919. Serial No. 269,972.

To all o; 710m it may cof/i oei/"n Be it known that l, Wimmer illumini?, a citizen ot the United States7 residing at Texarkana, in the county of Bowie and State of Texas, have invented new and useiiul Improvements in Inlet-Control. Valves tor Flush-Tanks, ot which the following' is a specification.

.This invention coniprehends generally improvements in that class oi inventions known as valves and more particularly relates to an inlet control valve lior flush tanks.

lt is the principal aiin and object of this present invention to provide a valve ot ther above mentioned character the construction et which is novel seing designed to act quickly under any head or pressure o'l water, to seat itsolt' truly at all times upon the valve seat, to ohriate Water hammering and to also close` noiselessly.

As an additional object the present iuvention contemplates the provision oi' a de vice oit' the above mentioned char eter wherein the valve is designed to 'automatically jclose with the. 'ater pressure in case of broken or detective float connecting rods or pins thereby eliminating the Waste oi water and leaving the several parts at rest without strain when closed.

More particularly the present invention conf' s in the ilarovision ot a device oil the above mentioned character wherein the attaching casing itself, cap, and the movable valve nieinoer and vthe valve stern are or novel construction and are peculiarly related with refpect to each other for Y ,turing1 of the a uloniatic closingi oi the valve when the witter roaches a predetermined level in the tank.

lt an additional object oi' this invention to provide a device ot the above inen tioued character which is simple in construction, thorough y reliable and eiiicient in its purpose and inexpensive in manufacture.

.ther objects will he iu part obvious and in part hereinafter set torth.

The invention accordingly consists in the features of construction, the combination of elements and the ar fangernent oi parts which will loe amplified, and the construction ot which will he indicated in the appended claims. Y

The invention is clearly illustrated .in the accompanying drawings, in whichM Figure l. is a transverse section through the flush tank showing the valve applied thereto and in elevation.

Fig. 2 is au enlarged vertical sectional detail of the valve in open position.

Fig. is a fragmentary vertical sectional detail showing the parts in closed position.

d is a transverse section taken on line lh-4 of F 2.

Fig. is an elevational detail of the czsing, and Y Fig. 6 is an elevational detail of the valve body.

Similar characters of' reference are einployed in all ot the above described views, to indicate ilorresponding parts.`

Referringnovx, more particularly, to the accompanying drawings there is provided a flush tank l of a conventional construction in which is operably mounted improved inlet control valve vgenerally indicated by the numeral 2. v

ln the present instance, the valve consists ot a cylindrical casing 3 which has depending therefrom an exteriorly threaded nipple Ll for insertion through the hottonr ot the tank for connection with the supply pipe 5 as at 6. The inner here i' ot the nipple has its upper portion, Where it coininunicates .vith the interior of the cylinder flared as at 8. The upper portion of the cylinifler is interiorly threaded as at 9 While mounted therein is a reduced threaded :portion l0 oi a hollow cylindrical cap l1. The hollow cap has its top and lower reduced portion provided with alining uopenings l2 While integral with and depending from the reduced portion is a sleeve i3 which alines with the lower opening l2. The cap is also provided with a horizontal rectangular Water outlet opening 'lil 'lor a purpose that will presently appear. llidahle through the alined openings l2 and the sleeve is a valve rod l5' the lower end ot which is threaded as at i6. il movable valve ineinber genenall);7 indicated oy the numeral l? is employed and consists or' a tubular portion i8 and a solid and inverted .conical head 19 which is integral with the tubular portion and which is provided with a threaded socket 2O .tor receiving the lower the tubular portion is provided with the Water inlet opening 2l while disposed Within
